Given numbers are 684, 392, 281, 108
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 392) = 67032
GCD(684, 392) = ( 684 x 392 ) / 67032
= 684 / 392
= 684
Step2:
LCM(4, 281) = 1124
GCD(4, 281) = ( 4 x 281 ) / 1124
= 4 / 281
= 4
Step3:
LCM(1, 108) = 108
GCD(1, 108) = ( 1 x 108 ) / 108
= 1 / 108
= 1
So, Greatest Common Divisor of 684, 392, 281, 108 is 1
